568-454 URETHANE 70 DURO ORINGS

APG stocks the U70454, an AS568-454 clear Polyurethane (AU/EU) 70 Shore A O-Ring with an inside diameter of 12.475 in (316.87 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 13.025 in (330.84 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Polyurethane (AU/EU) delivers very high tensile strength and load capacity, long wear life in dynamic reciprocating service. Expect good resistance to abrasion and wear, petroleum oils, and extrusion under high pressure. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Exposure to acids and bases or hot water and steam will shorten service life.

Common environments for this compound include mining and heavy equipment, hydraulic cylinders, and high-pressure fluid power.

Order part number U70454, sold individually. Nominal inside diameter is listed as 12 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design.
